3 PROJECT FACT SHEET DEWATS for a Slaughter House, Fish Market and Public Toilet Umred - Nagpur Project background A DEWATS unit was installed in a slaughter house, fish market and the public toilet complex in Umred, Nagpur. Umred, 45 km away from Nagpur, is a small township in Maharashtra, with a population of over 25,000.The wastewater generated from the slaughter house was earlier disposed off into the near by lake, which is of environmental concern to the Umred Municipal Council (UMC). The Project is funded by UMC. Type of Project Funding Agency Executed By Construction Cost : DEWATS SME for Slaughter House : Umred Municipal Council. : CDD-Regional Office, Nagpur. : Rs Lakhs Start of Operation : March 2012 Salient Features Source Slaughter House, Fish Market and Public Toilet Design capacity 22 m3/d No of users 600 Peak flow 8 h Purpose To reduce the level of pollution through wastewater discharged into water System in Brief The wastewater from the public toilet complex is collected in a settler for retaining heavier (settleable solids) and lighter particles (scum). The wastewater from the slaughter house is conveyed to a biogas settler, wherein the settleable solids settle at the bottom as sludge. Besides the settling of solids, bacteria degrade the organics present in the wastewater and the sludge is digested anaerobically. The anaerobic digestion leads to production of biogas. The wastewater from the biogas settler and settler is conveyed to an equalization tank. The wastewater from the equalization tank is further conveyed to an anaerobic baffled reactor (ABR) and anaerobic filter (AF). The ABR treatment modules which consist of a series of chambers ensure anaerobic degradation of suspended and dissolved solids. The baffle pipes of the reactor direct the wastewater stream between individual chambers from top to bottom. The anaerobic filter comprises of filter beds for treatment of dissolved organic matter in the wastewater. The wastewater comes in contact with an active bacterial mass which grows on filter material and on the walls of the reactor. The filters are filled with special filter media such as gravel, rocks, slag or plastic pieces. Modules adopted Biogas Settler : m3 Area of construction : 12.2 m2 Settler : m3 Area of construction : 12.2 m2 Baffle Reactor with Anaerobic Filter : m3 Area of construction : 38.0 m2 Planted Gravel Filter : m3 Area of construction : m2 DEWATS unit, Umred - Nagpur The wastewater is further conveyed to the planted gravel filter which is an aerobic tertiary treatment unit where the pollutants (mostly nutrients) in the wastewater are degraded aerobically. The treated wastewater is disposed into the nearby lake.

4 Construction Stages of DEWATS unit at Slaughter House, Fish Market and Public Toilet Umred - Nagpur RESEARCH ON SANITATION Pathway to Success: Compendium of Best Practices in Rural Sanitation in India The Ministry of Drinking Water and Sanitation, with the assistance of the Water and Sanitation Program (WSP) of The World Bank, has compiled a second volume on Compendium of Best Practices on Rural Sanitation titled The 16 success stories documented in the Compendium are lessons of inspiration and serve as models for various Gram Panchayats, Districts and States across India. These documents help overcome hurdles and obstacles in aspects of program implementation for addressing issues related to sanitation. Discover more INTERVIEW Mr. Mahesh K. R., Executive Engineer, Mysore Urban Development Authority(MUDA), shares his experiences during the Engineering Training Programme on DEWATS, 26th to 30th May 2014 Considering the growth of Mysore city in recent years and the spatial expansion of the city is largely contiguous and relatively compact. MUDA/ private developers have been in the process of developing new layouts. Besides, the residential layouts the private developers have lined up an array of proposals for constructions there are a definite need to oversee the sanitation infrastructures. Six officials of MUDA participated in the Engineering Training Programme on DEWATS to understand the construction, implementation and operation and maintenance of DEWATS. Mr. Mahesh K.R, Executive Engineer, (MUDA)

5 Did you find the training useful? I gained adequate knowledge and learned about DEWATS approach. As of now MUDA is trying to bring together strategies and capacities for improving sanitation infrastructure and to overcome the land availability issues for having STPs. Following the training programme we will identify the scope for DEWATS implementation. It was a great experience learning the design and implementation of DEWATS. I have also gained knowledge on the decentralised approach to wastewater and sanitation issues and now have enough understanding to adopt DEWATS approach for managing issues at the implementation level. Was the content of the training programme able to meet your expectations? Yes, the training was good and professionally done so that the participants could also learn about TM. sustainable sanitation approaches apart from DEWATS What is the scope of implementation of decentralsied systems such as DEWATS in and around Mysore? In some situations it is not possible to connect the drainage system of a property to the main drainage systems. With the prevailing growth of the city it is very feasible to implement decentralised systems such TM. as DEWATS particularly for private civil constructions such as apartments and housing colonies. Recommending and ensuring to developed and plan decentralised approaches will act as a solution for managing septage. NEWS AND VIEWS Situational Analysis of Faecal Sludge Management in Kommaghatta, Village by Internship Internship Students, interviewing the local-sewage vacuum tanker operators Training session on wastewater analysis While on a 5-week internship at CDD Society 2 students pursuing their bachelor s in Environmental Science from St. Joseph's College Bangalore conducted a situation analysis of sanitation in general, faecal sludge management in particular in the peri-urban area of Kommaghatta Village, Bangalore and at the way forward to improve the situation. Semi structured interviews with villagers, panchayat members and the local sewage vacuum tanker operators were conducted to obtain views of people on the infrastructure and the problems existing in the village. The students have prepared a comprehensive analysis which shows that the main problem with the handling faecal sludge in Kommaghatta Village is that single unlined pits are widely used. 92% of the households have in-house toilets. Grey water is disposed in storm water drains. Due to unlined open pits, effluent infiltrates into the soil and thus contaminate ground water.

6 th Workshop on Technology Options for Decentralised Wastewater Management, 5 June 2014, Bangalore CDD Society and BORDA in partnership with Rajiv Gandhi Rural Housing Corporation Limited (RGRHCL) conducted a Workshop on Technology Options for Decentralised Wastewater Management - Towards Sustainable Environment, with support from various Government departments of Karnataka (Water and Sanitation) and Confederation of Real Estate Developers' Associations of India (CREDAI).
